Yes. It's happened twice to me. I seem to have a knack for getting punctures! The good news is car handles exactly the same. The bad news of cause it that you can't repair the tyre even with a minor puncture because the act of driving on it writes it off. You are also only meant drive on a 'flat' for 250 km (155 miles) and at the same time also reduce your speed to 80 km/h (50 mph). It is really easy to forget about reducing your speed because the car doesn't handle any differently.

The only other thing I noticed was the tyre which was 'flat' got incredibly hot after driving only 30 km (19 miles), so hot that you if you had touched it it would burn you!

I had a flat not too long ago. Only thing to tell you is the run flat warning in the car. Would not know which is one has problem until you pump in the air. So now I carry a pressure gauge in the car to check!

I had a screw in the tire of my F30 328i a few weeks ago. It was a slow leak and I never noticed a difference, even after the TPMS alarm went off. I drove slowly to a gas station, filled up with air (tire was at 25 psi), then drove home. The next day, the air was low again, about 25 psi, and took it to the dealer, where a screw was removed from the tire and, fortunately, repaired and not replaced.

This is why you spend the sub-$500 (negotiated) on the 5 year/50,000 mile tire and wheel protection.

What if you purchase the warranty the day you get the flat? Will it still work? My dealership let me buy it after the fact (25 days) and I now have a ruined tired. THe analytics will show the warning came up prior though I am assuming right?

As far as I know, RFTs are as repairable as any tubeless radial. The trouble is if you drive on it while flat you are consuming the "run flat" rated mileage. So I am assuming if you fix it as soon as the flat is detected, it should be ok. Please note however that any fix, even on a tubeless radial, be it a patch or a plug or both nullifies the speed rating of the tire.

I bought my 328 on August 12th and I just had to have my passenger rear tire replaced this morning... $429 later... And that's with a discount they gave me because they felt bad!
Here's a picture of the bolt that somehow found it's way into my brand new tire...
I'm now looking to buy a set of wheels with normal tires and store the stock ones for when I go to turn the car in!

I hate to tell ou this, but even if you had a set of non run flat tires, you would have had to replace that tire. The bolt was on the inside edge of the tire, and is not able to be properly repaired. The outside edge is also susceptible to this. It is called bad luck. I had this happen to one of my tires, and I had to replace two of them since they were not brand new, and the wear would have been felt in the steering. So, be happy it happened early, if it was going to happen, since it cost you half as much as it could have.

I know I would've had to replace it regardless, but I would rather have replaced a normal tire than a run flat. It is bad luck and I am fortunate I was able to just purchase one. I'm still looking to replace the run flats with a set of normal tires and then put the run flats back on before I return the lease.
